Moisturizing Mechanism of Polyglutamic Acid: From the γ-Glutamyl Structure to Hydration Networks and Surface Film-Forming Behavior
γ-PGA is a natural polymer composed of numerous linked glutamic acid units. Industrially, it is generally produced by microbial fermentation using Bacillus species and other microorganisms. Depending on the microbial strain and production conditions, γ-PGA may consist of D-glutamic acid, ...
